Claims

[Scope of utility model registration request]

An on-off valve 1 and a synchronous motor 2 connected to a commercial AC power source are installed integrally, and a reducer 5 is interposed between an on-off shaft 3 of the on-off valve 1 and an output shaft 4 of the synchronous motor 2 to maintain a constant speed. In the electric valve that opens and closes the on-off valve 1, the on-off shaft 3 of the on-off valve 1 is provided with an on-off shaft stopper 6 corresponding to the open/closed position, and the motor controller 7 of the synchronous motor 2 is provided with an on-off shaft stopper 6. a commercial AC power frequency counter 9 with a reset circuit 8; a switching circuit 10 corresponding to open circuit rotation and closed circuit rotation of the synchronous motor 2;
A controller 11 of the switching circuit 10 is provided, and a controller 11 of the switching circuit 10 is provided.
operates the reset circuit 8 of the counter 9 and turns on the corresponding switching circuit 10 by inputting the open/close signal;
An electric valve controller characterized in that the switching circuit 10 is turned off at a preset count.
